This pie chart visualizes survival outcomes from a dataset, displaying the proportion of survivors versus non-survivors in a circular layout. The chart uses a D3.js v7 pipeline with `d3.csv` to fetch the data, `d3.pie` to compute arc segments, and `d3.arc` for path generation, with an ordinal color scale applied via `d3.scaleOrdinal` and `d3.schemeCategory10`. It renders as an SVG with a stroke outline, opacity styling, and a legend positioned to the right.
